Anything's possible... likely? No, it will take you millions of years to find a block on average. As for why they sell them to you, it's because it's easy to sell hardware to people who don't know what it is they're buying if the sales pitch is all bullshit.
I bought on Amazon UK, And sales pitch was that I could earn at least 25 bitcoin per month. If that's really not true I will raise an issue with Amazon You got flat out scammed. You'd need this much bulky, but still old hardware to earn that much; https://cdn.static-economist.com/sites/default/files/images/print-edition/20150110_WBP001_0.jpg |

Try lowering frequency to 150mhz to see if that brings the chips back online. Then work your way back up to 200MHz.
Otherwise, ask for compensation from seller.
I'll do that. Also if I move around the board connectors to see if the issue follows the board or the connector is that ok to do? Yep, I was going to suggest that if playing with the clock speed didn't help. Ok so at 150 it's stable with no X's but still missing 3 Asic chips on that board. I'll keep adding speed till it fails then back off one. After that I'll swap board connectors. Thanks for the help When you did hard reboots, did you unplug the miner for 10-20 seconds to power cycle? When i mess with voltage, i often have to unplug the supply to PSU for a while, until it click click, otherwise the PSU stays on even when you turn off the machine. |

2 S3's left and 2 C1's Left
Why are you not into water cooling? they actually make a great space heater it keeps my garage warm in the winter and with very very low noise
and they are very reliable never had any problems with them
Because there are more points of failures with water cooling and i already have fairly noisy miners, so having a quieter one would not really help with the noise. The trick atm is just using the winter cold air to keep the miner cold and drop the fan speed very low. At least that was the plan, with Elnino its frickin hot outside and we're in December. Anyhow since then i got bunch tons of mostly small miners and i capped out my grid, there is no more points in buying sidegrades anymore. I'd like to find myself some cheap warehouse or insulated office i could get industrial access to electricity but that does not seem all that easy(or cheap) to find. |

Pod dev is on hold right now anyway, until I get Compac manufacture caught up (which is to say, finished). If I did another batch I'd have to scrape up funds for a PCB order, and then I'd have plenty of time since it'd be 4 weeks out anyway. Once this batch of Compacs is finished my priorities will be pod dev and finishing out the hosting expansion install. Hopefully Novak's gotten our next PSU board prototyped soon so we can start talking about that too.
Novak and I's thoughts for a miner are, since we're looking at S1-formfactor, doing something with no more than about 220W stock setting per board. That gives you some headroom for fan and controller and should still come in under 500W DC power. That also gives you some room for overclocking if you want them to be nice and loud. 220W could be done off a single PCIe if you have good cables, but two would be more reliable. We like reliable. Now if only I can get some chips...
So basically, you're itching about designing a S1-like form factor PCB, but you'd like to do it with BM1385 gen-like chip, and not BM1384, so you're thinking about using the BM1384 for more stick, instead of a board? And a otherwise 220W per PCB with 2 PCI-e socket available would be awesome stuff. The underclockers would run it at 1 socket and the overclockers would run it at 2 sockets, with no limit other than not blowing up the chips/circuits when overvolting. |

A bit steering away from the topic for your intent to selling these miners. But i have some AM Tubes that i have quite a bit of problems running off the crap BE controller. I got a UART USB converter but i can't find a version of already compiled windows cgminer/bfgminer that works.
Might i bother you as to where you got your RasPi image to run these?

yes it is protected from all of that. Keeping my S5 in my basement as heater too.
It will be secure with a lock and soon a camera. ( theft... )
What do you have in mind Virosa ? I'm curious.
Nothing really, per your OP, since we both live in the great Poutine empire, criss, we have an electricity rate that make upscalling our home farms quite attractive/addictive, for me anyways. So if you had a few question then(about only 1-2 miners), maybe you'll have a few question later on. (10+miners) I think the thing that would make the biggest difference for my operation is switching to 220/240v. But seem kind of a pain to do it temporarily in an apartment i'm not supposed to be doing this in the first place. (Changing stuff) |

I would probably not seek to build a miner drawing more than 500W at stock setting. Whatever hashrate that gets me will be well below Bitmain's design targets of late.
Also, commentary on the idea of running out more Compacs with pulled chips? I'm pretty much at the end of my batch. I have two guys that need to get back to me about the orders they've requested, and if they both go through this batch is done.
In my selfish desires, as long as this does not slow down the design of a pod or even more interestingly a zero type board, this could be a good way to get you some more funds while you go through the designing and printing process of either of the other projects. A board that runs with 2 PCI-e sockets, 400w stock would leave a bit of headroom for OC from what i understand. 500W might not? Inb4 people start suggesting you make 3 PCI-e sockets boards.  |

I have three s-1's my zip code is 07731
I can pack the three in a schedule c flat rate box. So Postage is on me if you are close to NJ.
Ideal for the "free" power miner.
Please make serious offers under 90 usd for the 3 with the shipping included.
So for instance if you live in New York and offered me 80 bucks for the 3 they certainly would be yours.
If you live in New York and offer 59 bucks for the 3
I would say no.
pm's or posts are welcome.
At 25$ per S3, i'm pretty much interested, am i reading correctly, but i'm in Québec. Buying a single unit was prohibitive since one unit was 40$ shippinh, but as a bulk, the shipping might only go up to 50-60$, that might be doable. I will try to figure shipping. Montreal is in Quebec ? Send me your postal code. I deleted my post, as i realized i misread the title. Cheers. Hopefully someone that plan on trading in for for sidehack pods/boards can pick those up if you'd rather not hold on to these. |

Seems surprising that there is no minimum exempt amount.
The screws seem to be getting tighter.
Has anyone that posted here actually read the CIBC ANN? Its just basic KYC compliance. Its only very loosely related to Bitcoin and its already a rule implemented by most services most of us use for currency conversion. It does not feel like this is targeted at BTC in any way. Verifying your identity to allow linking a bank account and raising your buy/sell limit is exactly that. KYC. |

My S4 is now chilling outside, protected in a shed, ill upload pictures later. Nice temp.  Very much so, if your miner is protected from having water thrown on it during storms with high wind speeds, then this is a pretty good setup. Look like you got everything covered now, if you think of doing more than just expanding from there and need to bounce off some ideas, let me know. |

it's realy a damn that those threads are opened to ball breakers able to come to say you what to do ... and discuss it for 3 pages .... a waste of time, but you earn posts ...
Remember days ago i told you, if you accepted the offered escrow deal at that moment, you will get your money faster than if you refuse to use escrow? Well from what i understand, you still have not sold them, so this is what i meant; if you had listened to me then, you would be getting your money, now. =/ 3k USD is not an amount of money many people on the forum are willing to risk and write-off as an acceptable loss. Insulting and trashing about users that are telling you deal otherwise, is not going to be really productive. |

if voltage controller be in new boards. i think we can not control them  because pic12f1822 job is simple; adjust voltage at boot and set working voltage to buck controller ic. this is chip protection for them. If there is voltage control.... a way will be found to adjust it. Rich There's a voltage listing in /config/cgminer.conf on S7's. As someone mentioned earlier, the "factory defaults" are not the ones all miners come with though. Factory listing with 700 mhz is 0725, the one in some config files you'll see at receipt is 0706. It looks like this: "bitmain-voltage" : "0725" hate to break some bad news, but they put that in the s5 cgminer.conf too.. and the s5 definitely cant be voltage adjusted that way. Pretty sure the S7 is a string design, which apparently lead to not being able to set the voltage with software. You would need a buck step down instead. Not sure whats the big deal with their latest design schemes. Considering how much profit they make per unit, you'd think they could afford few extra bucks per boards manufactured to allow Volt control. |

Still for sale! HMu
show the miner with todays date for verification and your username WHy did you bump this from over a month ago, we all determined it was a scam and the OP disappeared. i didnt the OP did go back go back and read the comment above yours he deleted it Correct. I'm wondering if this should be subject to moderation. There's not proof per se that he is scamming, even though its obvious, can mod even ban him? I don't think this should be left around. At least this could be locked. |

What is the power consumption on this SP31?
When does the hosting finish?
They use like 3000 Watts. So unless you got cheap power, you might as well get an S7 since it almost the same price. You are right cheap power is needed but don't forget that for an S7 you need to purchase the psu which is an extra 150$, you need to pay shipping and wait until mid-end December for Delivery  It would make sense if he was referencing to the people selling used S7 for about the same price, which they are in hand and ready to ship and already within the country, saving you much more than 150$ in import fee/taxes. |

First thing : your coins are safe.
This type of problem I have faced many times with my multibit wallet. Just clicking the option of "reset blockchain", will re-synchronize and will show your bitcoins.
I had this problem so many time with Multibit Classic. Might be worth to note that i had not this happened to be with Multibit HD. Might be worth looking into. |

I got my batch 7 online yesterday and the noise is horrible and I used to think S5 is noisy.
Fans run over 4000rpm and blades are about 50C, air is traveling too fast, screams and resonates badly.
3 x DPS-600 powers take 1400W from wall, I tested power draw upto 1600W.
Customs took 1BTC for sale tax but I have "free" electrics as garage is heated with S7 so I maybe ROI some day.
What did you really expect? One S5 with one jet blaster fan was horrible noise pollution. Then, an S7 with two of them running. The temps aren't even the "real" temps. It's just a temp sensor on the board somewhere. I would always add 10 degrees to the temp shown. 50C, thats very good. You have some leeway here. Air is too fast, yes indeed it make a lot of noise at full speed; So why are you not reducing fan speed? 2 Fan is actually quieter than 2 fan because the air flow for the same noise is lower. |

Hi, I'm writting here for solve doubts about HWE% acceptable for Antminer S5. And, for example, the HWE% can going increasing and inflict a terrible damage in the miner? Other point, my miners #2 have a bad chip, 1X, and the HWE% isn't high, why? I going to attach the image here.  Good Vibes! I rather see the gui to tell your problems but it looks like 1 miner has 1 x which while not perfect is okay. note the image did not show for you because you are new. but I checked it and allowed it to show. I am not new and can do that. I rather se a two or three hour screen shot of the gui . I would like to know what psu's you use I would like to know the temps. I would like to know the psu. The fan speeds etc. but if you stay at the stats above for two or three straight days you should be fine. I'll try to capture it tomorrow in 3 times and I will upload the images, ok? But it's worth, this is the value higher in HWE%. I use some HP Server 1200W and some Super EVGA 1200W. The fan speeds almost always have 2-3 in 4080rpm and others in 3480-3900-4080. The temps is variable but the max is 60-62C, in the past image have 1 hashboard in 64C and other in 61C but already retouch the termic paste and all right. Miners have been all day on, just when I going to retouch the paste turn off, or networks problems sometimes, but the rest of the day 24/7. When I can consider dangerous in HWE? 0.01% maybe? Its not dangerous either, but its a hint of whether the power you're giving it is clean/at the right voltage. 0.1% either would not be dangerous, it would just be a good indication that your unit could be running better and at that point you are probably losing a bit of hashrate. For example, i can clock my S5's to 393.75 with 0 or near 0 HWE, with the EVGA's. Then i slap a Raidmax gold PSU, i get 0.3% HWE, slap a corsair, i get 0.08%. For the unit with a X, i'd try to power cycle it, if its still there and on the same chip, i'd try with a different PSU, preferably an EVGA if its not already on one. If its still X, then too bad, performance does not seem affected, its probably just that chip does not report properly. Like Phil said, its not what we'd like to see but it seem to otherwise be "ok". P.S.: I'd clean up some of those redundant tabs, so, so many tabs xD |

There are new laws that took affect recently and CIBC has implemented a new anti money-laundering requirement in all of their branches involving cash deposits. If you're purchasing Bitcoins, on localbitcoins let's say, and you choose to do a cash deposit into a CIBC bank account you are now REQUIRED to give the teller your name, address, occupation, date of birth and ID. If you already have a bank account at CIBC they can look you up and make a note that you're depositing $X into this other person's account. What does this mean? You can't anonymously deposit cash into a bank account anymore. Before all you typically needed for small amounts was a signature for the transaction. I thought I would pass on this info in case anyone was hoping to do a (somewhat) anonymous cash deposit into a CIBC bank account. I'm not sure if this has taken affect at all of the big 5 banks in Canada as of yet. Source: https://www.cibc.com/ca/small-business/business-accts/branch-transaction-requirements.htmlThe link provided is for small business accounts but it is the same case for personal accounts as well. It doesn't really seem related to Bitcoin much. Cash deposits done from bitcoin exchanges are not anonymous, this kind of sound more like a wire transfer from a person to another? |

no escrow???
SCAAAAAAAM!!!
I see nothing else to discuss.... only you getting your trust red and with minus
beffore ro speak about mu thrust see you'r an let me in peace man. Are these all for sale still, where in Belgium is the hardware?
Is escrow and/or meetup still not a option, I am in South of England so not a far drive for me?
i'm at the french/belgian/Luxembourg border in Arlon zone a little town near . yes it could be good , you plan to come from Calais by ferry ? stop talking rubbish and post a pic of the miners with ur username and date in it. otherwise close this waste of time thread photos has added the 2 december .. please read a thread before asking something already provided .... Look at your OP, they are not there. There are only dead links there. I did see them the other day, before they went down, but they don't do much anyways. |

I was asking about a payment... not joining. I've been here around 8 months.
I am aware of that mate, and neither did I quote you nor I addressed you, I don't see why you might think I'm replying to your post. On joining read front page: No New Spots! Enrollment is manual, please make an enrollment post.
If you bring something very special PM macro (very very few fit here chances are you do not). Best is to wait and watch thread, posting when closed is not going to help. Yes I am quite aware of that fact as well, but what is wrong in trying. Nothing, but you will have to do it the proper way. |
